IMPROVEMENT IN LUBRLIGA'ITING HUBS AND AXLES.

dilge tlgehule referat tu in tigen tethts ate1it mit making gmini the smite TO ALL WHOM IT MAY CONCERN:

Be it known that 1, THOMAS WILSON, of Garten, Yorkshire, England, have invented new and useful Improvements in a Perpetual-Lubricating Hub; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the'letters of reference marked thereon. i

The nature of my invention consists in providing a hub to a. wheel with anoil-rcceptacle or receiver and a perpetual-lubricating device, for vkeeping the bearing perfectly lubricated when required.

Italso relates-to enclosing the entire hub within a metallic case or shell, with joint in the middle, across its axis. f p A It further relates to the device which guards the bearing frown dirt, sand, &c.

To enableothers skilled in the art to make and use' my invention, I will-proceed to describe its construction and operation. l

Figurel represents an vend elevation of. my improved hub. 4 Figure 2 represents an end elevation with parts removed, showing the oil-receptacle andlubricatin'g-cle\'ice. Figurerlpresents a plan of the same. Figure llere-presents a longitudinal section of my improved hub. Similar letters in"`the different figures indicate corresponding parts. a represents the hub; b, the spokes; c, the'journal-box, which is secured to the hub a by the collars d and e. This box c is also provided-with arib, which prevents it from turning in the hub e. ff is the case, which is provided with suitable mortises, to correspond with the shape of the spokes 6 b, and is divided in the centre, as seen in iig. 3. Attached to the casef is th'e-.sand-guard y, h is a. nut which secures firmly the casef and ftogether, thus keepingthe spokes b b drin and in position. z'- is the oil-receiver, wbich'is secured to the'box c, and is provided with a cap, t", and glass,j','iin the same. 7' is the ailing-device, which is provided with its pistons ,Z l and valves m m. n 1t are oil-conductors, which conduct the surplus oil to the box. o is the axle, which is provided with its bearing,^p,having a. spiral groove, q, its entire length. This axle o is secured in and v to th'e boxlc by the cam-nut i), which also operates the pistons Z l and valves m m. The cam-nut c vis secured to the axlep bythe reverso-nut s; 'and t -is therwastebox, provided 'with waste, yarn, or thrums, for the absorption of the Waste-oil whichrinay :come from the oil-receiver z', and ndt used or required in lubricating, this chambcr t being attached tothe axle o. y 5

Operation.

The hub abeing thus arranged, and its several parts adjusted and secured in their res ective places, the axle-bearing'p, accurately'titted to the box c, and secured in the stime, is then ready for use. The oil-receiverz' is then filled with oil by aid of vthe bil-holes'c lr', and is then secured tothe ,box c by a screw. The wheel now being setvn motion by its revolution, the cam-nuto comes in contactfwithV the'pistons Z l, and lifts them vertically, opening thc valves m m, which allows the oil to pass from theQreeeptacle t' on to the oil-conductors n n, where it is caught'znd conveyed on to the end'oi' the box c, passing thence through the holes c' c on to the' Vbearing p, and ccnveyedits cnt-ire'le'ngth by aid of the spiral groove g and conducting-channels q in the`box c.

Y The excess and wnsteoil,`not wanted in lubricating the `journal p, is deposited in the waste-bont, and' retained, this box t forming a compressed air-tightjoiut.4 i

i Thus it \vill be seen, with this lubricating-device an axle can be lubricated an indeiinitclength of time, and

v'its bearing at the same timecompletely guarded and protected from dirt, sand, dust, Ste.

` And further, vby aid of the cas'efandf, additional strength and security can be given to the tenons of the `spokes?) b in the' hub a; and in case a spoke, b, is broken, a new'ono can instantly be replaced. And flirther, thc glass, 7", in the'cap z", serves both as an ornament and to expose to the operator the work,-` ings of the oiling-device.

What-I claim as my invention, and desire to secure by Letters Patent, is-

1. The cem-nut v, when arranged to operate substantially as described and set forth. 2. The' oil-receptacle j, in combination with the conductors n 71,' described.

3. The pistons ZZ, with their valves m m, when operated upon by a. cam-nut, v, substantially as herein described and set forth. u

4.; The sand-guard y and Wastebox t,

stantially as described and set forth. D

5. The arrangement and combination of the oil-receiver j, pistons l Z, with valves m m, conductors nu,

bo'x e, with its nuts d and e, bearing p, with spiral groove' q, Waste-box t, sand-guard g, shell f and f', and hub a., all wlren arranged substantially as described and for the purposes fully set forth.

in combination with the box c and bearing p, when arranged sub- THOMAS WILSON.
